Application filed March 24, 1908. Serial No. 428,000.

To all whom it may concern:

Be it known that I, Smcrmno GmoNooLI, a subject of the Emperor ofAustria-Hungary, residing at Zollfeld, in the Province of Carinthia andEmpire of Austria-Hungary, have invented new and useful Improvements inProcesses of Preserving Raw V.ictuals of Animal Origin, of which thefollowing is a specification.

This invention has for its object to preserve raw victuals of animalorigin, such as raw meat, venison, poultry, fish, crustaceous animals,eggs and the like during several months in unaltered state.

According tothe invention, the ieces of raw material to be preserved arerst provided with a complete, uninterrupted coating of solid fattysubstances, and afterward they are inclosed in an air-tight chamher,which is filled with a suitable gas at a pressure of from 2 to 5atmospheres. The gases which may be employed for this purpose, arerequire not to combine with the raw victuals and not to impart to themany taste or smell. Gases suitable for this use are, among others,dioxid of carbon (C0 7 sterilized air, nitrogen (N), oxygen (0),hydrogen (H), protoxid of nitrogen (N 0), nitric oxid (NO), methane(CH,) and othane (C H The fat to be applied may be of vegetable oranimal origin. In order to increase the adhesion of the fat to thebodies to be preserved, it is advantageous to emulsify the fat with athick solution of sugar; a concentrated extract of red beet well answersthis purpose. By emulsifying liquid fats with a solution of sugar, amaterial capable of solidifying is formed, and furthermore the emulsioncan be washed ofi' from meat with water.

The coatin of solid fat or emulsion is best applied y means of a coarsebrush, which serves for spreading over the bodies the naturally liquidor molten mass.

The victuals to be preserved remain in the air tight chamber, envelopedby the gas under pressure up to the moment of their being cooked forconsumption. Every time a piece of meat 'or other victual is to be takenout of the chamber, the gas under pressure is first to escape, thereuponthe chamber is opened, the piece of meat removed,- the chamber closedagain, and gas under pressure caused to flow into it again.

What I do claim, and desire to secureby Letters Patent is:

l. A process of preserving raw victuals of animalorigin, the saidprocess consisting in first coating the articles to be preserved with asolid fatty substance, afterward inclosing them in an air-tight chamber,filling this chamber with a suitable gas under a pressure of from 2 to 5atmospheres, and keeping up this pressure up to the moment of thevictuals bein cooked, the gas being not poisonous and 0 such a nature asnot to attack the article and not to impart to them any taste or smell,substantially as and for the purpose described.

2. A process of preserving raw victuals of animal origin, the saidprocess consisting in first coating the articles to be preserved with anemulsion of fat and solution of sugar, afterward inclosing the coatedarticles in an air-tight chamber, filling this chamber with a suitablegas under a'pressure of from 2 to 5 atmospheres, and keeping up thispressure up to the moment of the victuals being cooked, the gas beingnot poisonous and of such a nature as not to attack the articles and notto impart to them any taste or smell, substantially as and for thepurpose described.

3. A process of preserving raw victuals of animal origin, the saidprocess consisting in first coating the articles to be preserved with anemulsion of fat and extract of red beet, afterward inclosing the coatedarticles in an air-tight chamber, filling this chamber with a suitablegas under a pressure of from 2 to 5 atmospheres, and keeping up thispressure up to the moment of the victuals being cooked, the gas beingnot poisonous and of such a nature as not to attack the articles and notto impart to them any taste or smell, substantially as and forthepurpose described.

In witness whereof I have signed this specification in presence of twowitnesses.
